WHAT’S IT FOR? EQUIPMENT RATED FOR HIGH VACUUM + HIGH PRESSURE

Posted on: September 15, 2021

Complex machinery is no stranger to modern manufacturing. Whether it’s integrated into the high-end scientific research process, product research, development, testing, or the manufacturing process itself; pressure-rated vacuum equipment is becoming more and more commonplace. This leads many to wonder: what is it for?

First, let’s start by discussing the various types of high-pressure vacuum equipment.

Types of Vacuum Equipment

Vacuum equipment has several different kinds of classifications.

The first is the level of vacuum the equipment handles: HV, UHV, or XHV, standing for High, Ultra-High, and Extremely High vacuum levels. These have a variety of different applications, from on-planet research to satellites in outer space.

“The pressure range of XHV is usually defined as 10-12 mbar and lower, while UHV is between 10-7 and 10-12 mbar, and HV between 10-7 and 10-3 mbar. XHV is associated with the levels found in outer-space in the form of geostationary orbiting satellites, UHV with high-energy physics and nuclear research, such as that being conducted at CERN and KATRIN, and HV for industrial and research applications.” – Vacuum Science World

Making equipment that can withstand high vacuum environments has special considerations, including a design that reduces the number of seals involved, critical welding of the chamber, pre-treating the materials, and more.  Making equipment that is also suitable and safe for pressure requirements (ASME rated) involves even more specialized design, manufacturing, and testing criteria.  

Another classification system for integrated vacuum equipment is whether it is Basic, Intermediate, or Complex:

— Basic is a light kit that integrates the chamber, frame, pump, and plumbing, ready to use. It is minimally complex, ready to use, and inexpensive compared to more complex vacuum equipment.

— Intermediate vacuum equipment includes the above but also has more controls and gaging added on. These often include more computerized monitoring and remote logging for data handling.

— Complex systems are more stand-alone, with integrated power supplies, instrumentation, and more. They are the most comprehensive, most expensive, and can be tailored to the needs of the research, development, or testing operations using them.

Vacuum equipment is commonplace throughout science and industry, but what purpose does it usually serve?

Uses for Pressure Rated Vacuum Equipment

There are many reasons why vacuum technology is used throughout the industry. Research. The cutting edge of modern science, pushing the boundaries of our understanding of physics and the universe as we know it, uses vacuum chambers for a variety of reasons. Our equipment is even in use at UCLA, working on detecting neutrinos and solving the dark matter problem.

— Testing. Many products, from those used in scientific testing to those shipped into outer space, and even those used in potentially high-pressure environments, require vacuum testing. Equipment that includes vessels rated for high vacuum and high pressure are needed to appropriately test materials and products before putting them into use.

— Cooling. Pressure and temperature are intimately connected, and by reducing pressure, you can reduce temperature. Vacuum systems are used as part of cooling and cryogenics in research and manufacturing.

— Integrated vacuum systems are modular or comprehensive and can be custom-designed to suit any need, be it scientific or as part of a manufacturing process. 

High-Vacuum & High-Pressure Performance

Vacuum equipment is critical to the success of a variety of processes and experiments around the world. Vacuum equipment that also involves ASME and other pressure criteria is even more critical.  As such, the quality of the equipment in use needs to be impeccable.
